Scientists study stormwater, deadly to salmon

Just hours into the experiment, the prognosis was grim for
salmon that had been submerged in rain runoff collected from
one of Seattle’s busiest highways. … The research being
conducted by scientists with NOAA, Washington State University
and U.S. Fish and Wildlife offers a promising solution to
stormwater pollution, a major problem for Puget Sound and other
streams and lakes in the nation.
